Mitigating the effects of a broken (physical) screen

I don't know how large my screen is exactly, but suppose it's 800 (rows) x 1200 (columns). Around 50 columns about 900 columns to the right from the left side are corrupted. It's not quite clear what the error is, but some colors are better represented than others.
(I do know that the corrupted pixels all seem to behave in the same way: if they are asked to show a color C, they instead show a color C'. The mapping C->C' seems to be the same for all pixels.)
I don't want to fix the computer physically. Instead I have a two-step plan:
1) Check what the error is exactly, by checking how various colors are represented (manually, of course, by necessity).
2) Once I have an idea of what colors to replace by others, do that automatically.
My question is primarily how to achieve 2 in the most 'Linux correct' way. Tips on how to do 1 are most welcome!

I don't think there's an easy way to do this, but with many kinds of screen damage, the damage will not be mitigatable - e.g. if all the green values of the pixels are set to 0. So it depends on the kind of damage.
